I use the gui "nvidia-settings" to change my display configuration between the internal laptop screen and the external monitor at work (I always set one to off and the other one to auto). Is there an automatic way of doing that from command line? so I don't have to open the GUI all the time and navigate to the options with the mouse. I've checked all the "nvidia-settings" parameters but could find anything...

Unfortunately I've tried the "nvidia-settings -tq ProbeDisplays" or the "nvidia-settings -q AssociatedDisplays" methods and they are not useful for what I'm trying to do. If I execute both commands with both display configurations (one with the internal monitor on and the external off and the other way around) I get the same hexadecimal code for both :-?
